session_start(): open failed: No space left on device (28)
I occasionally receive this error on my sites.
I've checked the /tmp/ folder and it's not even close to full.
hero@vps [~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/vda1 30G 16G 13G 57% / none 504M 0 504M 0% /dev/shm /usr/tmpDSK 2.0G 587M 1.3G 31% /tmp
At the same time, some other site has the following error:
Fatal error: Call to a member function get() on a non-object in /home/memeflor/public_html/index.php on line 105
Sometimes they will just back to normal by itself. But the error will happen again some other times.
Does anyone have any advise on this?
